Description
Technical field
The present invention relates to a kind of spinning fiber sizing material.
Background technology
Be accompanied by environmental protection tide that world wide starts and growing new fiber species, China spinning sizing agent development and application worker is faced with 2 unavoidable practical problems: the sizing technique of fabric fiber and the development technique of green slurry.
Size performance, sizing equipment and slashing technique have extremely important status in the cotton spinning industry.Therefore, require to update size performance, improve stock quality according to textile sizing; Plan as a whole each the link coordinated development of slurry, sizing equipment and slashing technique, work in coordination; Develop the alternative slurry of function admirable, few with or without PVA; Development is suitable for the slurry of extra-high-speed Zhi Gaomi kind starching comparative maturity; Development tencel yarn sizing slurry; Study biodegradable PVA slurry and reclaim difficult degradation PVA technology cheaply; Explore the mechanism of action of nano assistant; Promote slurry and slashing technique technical merit; Be slurry, sizing equipment manufacturing enterprise and very difficult task of cotton spinning industry.
Textiles has one important operation before weaving be the warp sizing operation, at present, institute's spreading mass mainly contains three major types: starch (comprising converted starch), polyvinyl alcohol (PVA), acrylic compounds (comprises Barbiturates, amide-type, the ester class), in China's slurry, generally all based on PVA, though the PVA slurry has good adhesive force to fiber, and serous coat is tough, ABRASION RESISTANCE is good, once once be considered to ideal slurry, but because of its cohesive force surpasses its adhesion greatly, the easy skinning of slurry surface not only in the starching process, cause slime spots, influence sizing quality, and the dividing sinker resistance is big, sizing hairiness is many, in addition, the critical defect of PVA is the pollution to environment.Because PVA is more stable with respect to soda acid and general microorganism, is difficult to fall the angle in natural environment.Though its physics oxygen demand (BOD) is very low, COD (COD) is very high, and the latter makes desized wastewater cause bigger harm to environment.Therefore, in the world the main body entrance state of some fabric clothings and area one after another by legislation or formulate corresponding standard and come strict the monitoring carried out in the security of the fabric clothing of institute's import.This just requires to develop out to human body and environmentally friendly textiles and spinning sizing agent.Some developed countries of Europe, the United States have classified PVA as in " unclean slurry ", forbid to contain the textiles import of PVA slurry.
Retrieval Chinese patent textiles slurry, on September 17th, 2003 Granted publication " a kind of fabric size ", it is characterized in that it is a kind of nanoscale colloidal sol, or nanoscale colloidal sol with can make yam surface by the composition of membrane substance, both percentage by weights are 3-5: 1.It is described that to make the material of yam surface tunicle be some resin monomers, promptly contain-CHO ,-C=O ,-COOH ,-OH ,-C=C-,
-C ≡ C-, O=C-NH
3OH ,-C-NH
2The material of active gene.Slurry of the present invention is because the permeability of nanoscale colloidal sol is extremely strong, and since in the hydroxyl on its solid particles surface and the fiber hydrogen effect of formation hydrogen bond and strengthened the fibre strength of yarn through baking dehydration.Its enhancing rate is 10-15%.
On June 22nd, 2005, Granted publication " preparation method and the slurry of castor oil modified polyarylate graft copolymerization spinning sizing agent ", the invention provides a kind of preparation method of castor oil modified polyarylate graft copolymerization spinning sizing agent, be characterized in: the first step, with castor oil and phthalic anhydride (benzene liver) and maleic acid anhydrides and polyethylene glycol raw material, synthesize novel castor oil modified polyarylate through the macromolecule polycondensation reaction: second step, the graft copolymerization spinning sizing agent is characterized in: slurry is high concentration emulsion form or powdery granule.Hydrophobicity chemical fibre and natural fabric all there are higher adhesion, good water solubility, pliability is good, and the powder compatibility is good with rushing down, and the viscosity ratio acrylic size greatly reduces again, overcomes the shortcoming of PVA.
These two patented products all are that part has replaced PVA, can not replace fully, still can not break through " green barrier " of International Textile; On some degree, strengthened simultaneously the cost of enterprise again, the complexity of sizing mixing, operation is loaded down with trivial details; The cost of making and produce slurry is too high, adds the cost of large enterprises.Therefore, till now, the environment-friendly size that China does not also have to replace fully comes out.And the sizing bodyguard just is being based on the new green environment protection spinning sizing agent that the textile industry present situation is developed.
So-called environmental protection spinning sizing agent mainly is: 1, this slurry in producing, using to the ecological environment of low pollution or do not pollute; 2, in production, use slurry process, reach final products and will help health, do not jeopardize human life security; 3, producing, using in the slurry process and will save the energy, water source; Lack usefulness or, utilize regenerated resources to greatest extent without non-renewable resources.In a word, the basic demand of environmental protection slurry mainly is that its raw material (corn, cassava, potato etc.) is not subjected to the Insecticides (tech) ﹠ Herbicides (tech) residual contamination in growth course, use recyclable, degradable raw material as far as possible, in process of production environment, human body are not caused adverse effect.
Slurry has the approach that environment pollutes: at first be that starch produces the waste water that contains a large amount of fibers and partly dissociate fat, albumen, starch etc. in process of production, when degenerative treatments, have residual medicament, reach a large amount of salts discharges; Slurry in use can clean mixing cirtern, can only discharge because of being difficult for preservation surplus slurry, its waste water will not pollute as treated yet: textiles weave finish after, also the slurry on the fabric must be returned, the waste water that washes down also must could discharge after treatment; The pollution that PVA causes is even more serious, and poor because of the PVA biodegradability, recovery cost is tall and big, the cost height.Waste liquid directly discharging meeting belongs to the contamination type slurry because of there is aerobic substance severe contamination water quality such as COD and BOD.
Promote the approach of environmental protection slurry: 1, replace the PVA slurry as far as possible, as utilizing starch conversion, make it improve serous coat pliability, adherence, permeability, ABRASION RESISTANCE, part substitutes PVA.2, reclaim PVA as far as possible, producing the slurry that high, high density fabric fashion do not have alternative PVA, so developed country taking to reclaim PVA in the destarch with membrane separation technique, so that reuse, minimizing is to the pollution of environment.3, acrylic size is used in exploitation, it is generally acknowledged that acrylic size belongs to environment-friendly size, but to adjust the acrylic monomer kind, ratio is made and can be satisfied the starching requirement and pollute less slurry.4, change production technology, reduce slurry consumption and discharge of wastewater as far as possible.As the slashing technique of " two-supremes one is low " (high pressure, high dense, low sticking), this technology can not only reduce pollution, cut down the consumption of energy, and can improve the speed of a motor vehicle, loom efficiency and product quality.

Should not contain following harmful substance in the slurry
1, carcinogen: mainly be formaldehyde in the slurry.Formaldehyde also can produce strong impulse to the respiratory tract and the skin of human body except making the human carcinogen, causes respiratory inflammation and dermatitis.Formaldehyde also has the strong impulse effect to eyes, and internal organs and mucous membrane etc. are caused serious injury.Therefore, China implemented the state compulsory standard of GB18401 on January 1st, 2003, and the content of formaldehyde of all textiless and textile fabrics has been carried out strict qualification.Some phosphates also are put into carcinogen, mainly appear in starching in phosphorous auxiliary agent and the phosphatic use.
2, chloride, the organic matter and the most chloride that contain phenyl ring: as these chlorides such as pentachlorophenol, tetrachlorophenol and naphthols not only itself is Environmental Hormone; Enter after the destarch in the sewage, because it is they are more stable to the Natural Degradation process, harmful to environment.They are own poisonous, contact the back with human body and produce the biological accumulation effect, and human body is had teratogenesis and carcinogenesis.
3, harmful heavy metal: this also often is detected in slurry.Mainly be in the slurry manufacture process, introduce in the used chemical raw material, when especially using underproof chemistry examination auxiliary agent to produce slurry.For example: the impurity when producing modified starch size in used clorox, phosphate, urea or the like chemicals.A collection of heavy metallic salt listed in the table 3 contacts with human body, in case be absorbed by the body, then can accumulate in liver, bone, kidney, the heart and brain, after to a certain degree health is caused huge injury.For example: nickel contacts the spot of punishing severely that can cause skin for a long time with human body, is placed restrictions on by strictness.
4, be difficult to biodegradable material: the most outstanding with some surfactant in the existing slurry, some esters of acrylic acid slurry is also than difficult for biological degradation.They can damage ecological environment.
5, the pH value exceeds optimum range: we know that human body skin is faintly acid, to prevent the intrusion of germ.If be strong basicity or highly acid with the clothes of contact skin, can cause damage to skin.This to baby and skin sensitivity person more so.PH value on this main therefore textiles in neutrality to the most useful between the faintly acid to skin.Slurry pH value is also carefully for being
6, unusual odor: smell is to feel to the people by people's olfactory system.Unusual odor master is that chemicals causes, they are Diazolidinyl Urea and mucous membrane also, can cause conjunctivitis and dermatitis etc.Therefore in process of textile production and in using, also provide certain restriction.This often occurs in the acrylic size commodity.Peculiar smell detects and adopts the people to pass judgment on for sense of smell
The ecological limiting value of fabric clothing
Natural ative starch is a green material beyond doubt, be easy to by biodegradable natural macromolecular material, be an out and out green material (annotate: but the green problem should control agricultural chemicals, fertilizer and produce starch when plantation the time), it will have great development.
Sizing bodyguard slurry is the macromolecule polysaccharide that extracts with from natural bean (cluster bean), is base-material with galactolipin, mannose and cationic hydroxyl sal-ammoniac, and it is formulated to add various auxiliary agents, meets above-mentioned requirements.
Embodiment 5 preparation methods
The graft copolymerization of starch has three kinds of fundamental reaction types: wet method, dry method and gelatinization grafting method.Since dry method grafting method have the power consumption of non-wastewater discharge, drying less, product yield height, many advantages such as technology is simple, cost is low.For this reason, sizing bodyguard product has adopted the production method of starch dry method graft process.
The characteristics of dry process are that reaction monomers and other organic reagents are dissolved or dispersion with low amounts of water, are sprayed on the starch and stir graft copolymerization under dry heat condition.Owing to there is not enough water, although reaction temperature may be higher than starch gelatinization temperature, the reaction afterproduct still can keep the starch granules shape.Be characterized in that course of reaction does not have discharge of wastewater, the drying power consumption is few, the product yield height, and technology is simple.Adopt dry process to produce sizing bodyguard slurry, can remove power consumptions such as a large amount of preliminary treatment, washing, filtration, drying, operation consuming time from, have plurality of advantages such as production efficiency height, cost are low, non-wastewater discharge.
For example: by prescription metering with the ative starch spiral belt dry process reaction device of packing into; The closed reactor mouth is pressed into initiator solution with nitrogen, fills the nitrogen exhaust 10 minutes; With being steam heated to set point of temperature, be pressed into monomer with nitrogen after 30 minutes in the chuck; The reaction heating, system is from heating up; Kept this thermotonus 3 hours.Course of reaction remains stirring.Reaction finishes, and opens the reactor upper air vent, starts air exhauster, gets rid of steam, is cooled to below 40 ℃, from reactor end opening discharge, pulverizes, and screening packs after the wet balance in air.
The principal monomer that dry process uses is a hydrophobic monomer, and the surplus basic body of the glucose of starch is rich in hydroxyl, belongs to hydrophilic macromolecule.Because hydrogen bond action is very strong between the starch molecule, decreases easily after making slurries.Behind grafting hydrophobicity side chain on the starch polymer main chain, intercept or weakened hydrogen bond action between this molecule, the slurries good stability of consequently making can not cool off back dehydration gelling as the ative starch slurries; And because the hydrophily of starch main chain, have that the graft starch of a certain qualification content hydrophobic monomer is still solvable in hot water maybe can be disperseed.
6, production process: complete set of equipments mainly comprises: mixer, automatic weighing machine, automatic feeder, high-pressure reactor, dryer, screening machine, grinder, automatic packaging machine etc.Material-transporting system is made up of unwheeling, guide rail, pulley and automatic switching control equipment.Wherein, unwheeling, guide rail are guaranteed anticorrosion more than 20 years all through preventing flow of metal and galvanizing technical finesse.Its mass transport pulley and automatic switching control equipment can make things convenient for, easily carry out mass transport, guide rail automaticallyes switch.
Five, slurry has the approach that environment pollutes: at first be that starch produces the waste water that contains a large amount of fibers and partly dissociate fat, albumen, starch etc. in process of production, when degenerative treatments, have residual medicament, reach a large amount of salts discharges; Slurry in use can clean mixing cirtern, can only discharge because of being difficult for preservation surplus slurry, its waste water will not pollute as treated yet: textiles weave finish after, also the slurry on the fabric must be returned, the waste water that washes down also must could discharge after treatment; The pollution that PVA causes is even more serious, and poor because of the PVA biodegradability, recovery cost is tall and big, the cost height.Waste liquid directly discharging meeting belongs to the contamination type slurry because of there is aerobic substance severe contamination water quality such as COD and BOD.
The present invention is not limited to above-mentioned preferred forms, and other any identical with the present invention or akin products that anyone draws under enlightenment of the present invention all drop within protection scope of the present invention.
